Vandermonde and Euler class

[edit]

I'm not familiar with the relation between the Vandermonde polynomial and the Euler class. This section needs more explanation, and a reference would help.

Agreed. I think that the splitting principle relation of the Euler class to the top Pontryagin class is more that the square of a pfaffian is the determinant. Mike Stone (talk) 21:13, 28 July 2013 (UTC)[reply]

construction of orientation class

[edit]

An orientation of amounts to a continuous choice of generator of the cohomology

of each fiber relative to the complement to its zero element .

Would somebody mind elaborating, how to get this relative cohomology class? Thanks, Jack

You can get it from Thom Isomorphism
